In Buddhist ideology, the conventional self is that which is constructed in a way by the use of the pronoun, and when you realize there is no absolute ego there, no disconnected one, self, or ego, then that actually strengthens your conventional ego. It does so in the sense that then you realize it's a construction, and you can strengthen it in order to help others, or do whatever you're trying to do, it's not like you no longer know who you are. Then you can organize your behavior by using your ego, as it's now the pronoun. -
